I only just discovered KBS World on YouTube! I streams live 24/7 with new Korean Dramas as well as some old ones, new TV show episodes, and entertainment news! ^_^
In terms of dramas, I watched Music Lovers/Lovers of Trot and I’m currently watching Discovery of Romance and Radio Romance. I saw the ending of Jugglers but I will look for that online from the beginning.
Other shows I love are Immortal Songs 2, Return of Superman 2 and Hello Counselor sometimes.
